This is nice rum. Both beginners and intermediate drinkers could appreciate the sweet vanilla-toffee smell and strong but sweet taste, the nice acidity and tardiness which bourbon barrel brings. But there is also sweetness of molasses and the specific alcohol rum taste. It looks like match in heaven, but sadly it is lacking. One glass is nice experiment, but with second one you start wondering why would you want to drink more. You can get the bourbony notes better with some nice bourbon and the same with rum notes. So Black Barrel worth keeping for taste exercises? No, but it's worth the try if you stumble upon a nice price.
